Dynamax Isata 3 Water supply

[Work]

Our Isata 3 (2018) has a water supply inlet for city water only. There is no gravity fill option so when you are on the road or in a campsite for extended periods, there is no way to refill water. Is there a work around or alteration to fill from a portable tank with a pump or gravity feed from the inside of the RV bathroom somehow which I’d located just above the water tank??

Welcome to the forum its a great place to get your questions answered. check your water panel (where the city water enters) and see if there isn't a valve for filling the FW tank. I'm sure someone not he forum with the same rig will answer your question better then I have.

There is no valve.
